Operating Ranges
The W3011 operating ranges are shown in Table 3. Performance is not guaranteed over the full range of all
conditions possible within this table. However, the table lists the ranges of external conditions in which the
W3011 provides general functionality, which may be useful in specific applications, without risk of permanent
damage. The conditions for guaranteed performance are described in Tables 4 and 5.
